HFA100
Multicontact Auxiliary Relays
For AC and DC circuit applications.
Description
HFA Century Series relays are designed for
applications where a number of auxiliary
functions must be performed simultane-
ously. The Century Series coil design
provides longer operating life than
previeous designs as a result of changes in
the entire coil insulation system.
The six electrically separate contcact
circuits are adaptable for either circuit-
opening or circuit-closing applications. If
more than six circuits are to be controlled,
the coils of two or more relays may be
connected in series (DC only) or in parallel.
HFA Century Series relays are offered in
non-drawout case or drawout case
construction.
Non-drawout cas HFA relays are available
for front connection (suitable for surface
mounting only) or back connection (suit-
able for semi-flush mounting only).
Drawout case HFA relays are back-connect-
ed and are suitable for either semi-fluch or
surface mounting.

Electric Reset Relays
TABLE A lists the combination of reset and mounting avail-
able.
TABLE B lists the voltage and frequencies of the operating
and reset coils.
TABLE C shows the variaous contact configurations avail-
able.
To obtain a complete catalogue number, select the basic
number from Table A; insert the form number from Table
B; specify the contact code fromTable C.

ቢ On hand and electric resetTypes HFA154B, 174B, 154E
and 174E one contact is wired in series with reset coil
to provide positive cutoff.Thus five contacts are avail-
able for external circuits.
